because subtitles streams will be written to webvtt m3u8 list so the stream index should minus subtitles streams count when subtitle between audio and video streams. testcase: before patch: ffmpeg -i input -map 0:a:0 -map 0:s:0 -map 0:v:0 -f hls aaaa.m3u8 will EXC_BAD_ACCESS after patch: ffmpeg -i input -map 0:a:0 -map 0:s:0 -map 0:v:0 -f hls aaaa.m3u8 will ok
